K2M introduces Sahara AL expandable stabilisation system


K2M has launched the Sahara AL expandable stabilisation system, the company’s first expandable product within its interbody portfolio. Sahara AL is the only lordotic expandable interbody device with integrated screw fixation on the market to help achieve spinal balance.

The Sahara AL system is designed to allow for in-situ lordotic adjustment to match a patient’s sagittal profile through one fusion device. Sahara AL is a zero-profile device with multi-screw fixation, designed to provide stability to the anterior column, while featuring a range of lordotic adjustments of up to 26 degrees. It is indicated as a standalone device for lordotic angles of 15 degrees or less. The device is manufactured from commercially pure grade II titanium, titanium alloy, and cobalt chrome.

“The anterior-lumbar interbody fusion (ALIF) approach allows for greater segmental lordosis correction and implant fixation than other alternative interbody approaches,” said Christopher Good, an orthopaedic surgeon and director of Scoliosis and Spinal Deformity at The Virginia Spine Institute in Reston, USA. “With variable in-situ lordotic adjustment, the Sahara AL implant helps achieve sagittal balance and segmental reduction not generally attainable by ALIF cages with fixed lordotic angles.”

The device features K2M’s Tifix locking technology, which is designed to allow, for example, repeated screw adjustment up to three times, without compromising the locking feature. In addition, Sahara AL features a variety of footprints and heights intended to best fit patient anatomy.
